CAN-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 415,994, dated November26, 1889.

Application filed February 18, 1889.

To (0% whom it may concern:

Be it known that I, EDWIN E. ANGELL, of Boston, in the county of Suffolkand State of itlassachusetts, have invented certain new and usefulImprovements in Oan-Body-Holding Mechanism for Can-Heading Machines, ofwhich the following is a specification.

This invention has for its object to provide improved automatic meansfor supplying cylindrical bodies to machines in which flanged heads areapplied to said bodies and the supporting or clamping said bodies duringthe operation of applying the heads.

The mechanism which constitutes the subj ect-matter of this applicationis shown in another application, Serial No. 300,249, filed by meconcurrently herewith, for improvements in can-headin g machines, towhich application reference may be had for a full description of thegeneral operation of the machine.

The invention forming the subject of this application consists in thedetails of mechanism,whereby the can-bodies are supplied, held, andreleased, which I will now proceed to describe and claim.

In the accon'ipanying drawings, forming a part of this specification,Figure 1 represents the can-body supplying and holding mechanism, theclamps being separated prior to being closed upon the can-body. Fig. 2represents a similar view showing the clamps closed. Fig. 3 representsaview taken at right angles to the view shown in Figs. 1 and 2. Figs. 4,5, and 6 are views showing the can-feeding uates the same.

The same letters of reference indicate the same parts in all thedrawings.

In the drawings, Ct represents a chute through which can-bodies are fedto the mechanism which applies the flanged heads to the ends of thecan-bodies, said bodies having been previously formed into cylindricalshape and soldered by suitable mechanism for example, such as is shownin prior applications for improvements in can-soldering machines Thecans are allowed to drop one at a time from the chute by a feedingmechanism, hereinafter described, upon a movable support or arm I),which is mounted to swing on a fixed rod or support 6, attached SerialNo. 800,250. (No model.)

to the frame of the machine, and is operated by a cam, hereinafterdescribed, so as to stand under the chute a and between the can-bodyclamps c c, in position to arrest and support a can-body dropping fromthe chute until the said clamps clasp the can-body, and ,then move away,so as to be out of the way of the devices that apply the heads to thecan-body. Said arm or support I) has stops or projections b, whichretain the can-body in place and prevent it from moving endwise. Theclamps c c are semicircular and are arranged at opposite sides of thepoint where the can-body is supported by the arm I), said clamps beingattached to the upper ends of levers (Z (I, the lower ends of which arepivoted upon the rod 6.

f represented a driving-shaft journaled in bearings in thesupporting-frame and provided with a series of cams whereby motion isgiven to the different parts of the machine. The can-supporting arm Z)has a trundle-roll b", which is engaged with a cam-groove g in a disk gon the shaft f, and is thereby given an 7 5 oscillating motion, asdescribed.

The levers cl d are provided with trundlerolls which enter cam-grooves hin disks h h on the shaft f, said cam-grooves being formed to move thelevers (Z (Z and the clamps o 0 8o thereon alternately toward and fromeach other, thus closing the clamps upon a canbody, as shown in Fig. 2,while said body is supported by the arm I), the cams being timed to holdsaid clamps upon the can-body while the heads are being applied thereto,and to then separate the clamps and to allow the headed body to dropinto a chute j, through which the can-bodies pass from the machine toanother machine or floater which solders 9c the heads.

The cans are released from the chute a one at a time by a feedingmechanism composed of two slides or arms A A, which project in oppositedirections into slots D D in said 9; chute, and are connected to a shankor holder B, which is attached to the upper end of a lever O. Said leveris mounted to swing upon the rod 6, and has a trundle-roll F, whichenters a cam-groove G in a disk H on the shaft I00 f. The rotation ofsaid disk oscillates the lever O and causes it to reciprocate the slidesA A and thereby simultaneously move one slide into and the other out ofthe chute a. Said slides are separated by a space about 1 equal to thediameter of one can-body, and

when the lower slide A is moved out from the chute the can-body thereonis released and allowed to drop, the slide A being at the same timemoved inwardly to arrest the next can-body above. After the discharge ofthe can-body the slides A A are moved in the opposite direction, theslide A being thus moved into the chute to arrest the lower canbody,which is allowed to fall upon it by the outward movement of the slide A.

It will be obvious that the devices above described for letting 01f,clamping, and releasing can-bodies may be used with any other suitablemechanism for applying heads to can-bodies while they are clamped, myinvention not being confined to the can-applying devices shown in theabove-named application.

The clamps c c are adjustably secured to the levers d (l by means ofbolts a passing through slots in the shanks of the clamps. Screws 0working in tapped sockets in ears on the let ers (I, support the clampsat any point to which they may be adjusted and p revent them fromslipping on the bolts 0 I claim 1. In a can-heading machine, thecombination of the can-body-delivering chute a, the connected slides A Aarranged at different heights in the chute, the lever O, supporting saidslides and pivoted at one end to a fixed support, and the shaft f,having a cam G, engaged with said lever, as set forth.

2. In a can-heading machine, the combination, with a can-body-deliveringchute, of the clamps c c, mechanism for opening and closing the same, acan-supporting arm, and mechanism for holding said arm alternately underand away from the clamps, as set forth.

3. I11 a can-heading machine, the combination, with acan-body-delivering chute, of the clamps c c, the levers d d, supportingsaid clamp, the cams h h, whereby said levers are oscillated, thesupporting-arm b, and the cam g, engaged with said arm, all arranged andoperating substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 31st day of January, A. D.1889.
